Application filed December 19,, 19112. Serial No. 737,591.

To all whom it may concern:

Be it known that l, VVLLLABD. F. RioirARns, a citizen of the United States, residing at Depew, in the county of Erie and State of New York, have invented a new and useful Improvement in Railway-Car Trucks, of which the following is a specification.

This invention relates tocar truck side frames, and more particularly to means for securing the journal boxes to side frames of that kind, now well known, which are provided at their opposite ends with integral depending jars or parts that straddle and hold the journal boxes in place in such a manner that the journal boxes, together w th the car wheels and axles, can be readily removed from the track by raising or jacking up the side frames. Retaining means of some sort are ordinarily provided for preventing the accidental dropping of the journal boxes from between the frame aws which might otherwise happen, for example, if the truck left the track from any cause.

The objects of this invention are to produce strong and reliable devices for retaining the journal boxes in the jaws, which are of a novel construction adapted to be readily operated to secure and release the journal boxes and have means for releasably holding them in their operative position; also to improve the construction of devlces of this kind in the respects hereinafter specified.

In the accompanying drawings: Figure 1 is a fragmentary side elevation, partly in section on line 1-1, Fig. 2, of a car truck embodying the invention. Fig. 2 is a plan view thereof, partly in section on line 22, Fig. 1. Fig. 3 is' an end elevation thereof.

Like reference characters refer to like parts in the several figures.

A represents the metal side frame of a car truck which is provided at each end w th integral depending portions a a formlng rigid jaws between which a j0urnal box B is held. Except as hereinafter described, the side frame may be of any suitable construction but preferably consists of steel casting of the form shown in the drawings. The side walls of the journal box are provided at their outer faces with ribs 7), between which the depending jaws a a of the side frame are adapted to enter for holding the journal box from lateral movement relatively to the frame. Preferably the deor seat in a depression f pending jaws a a of the side frame do. not extend downwardly to the full depth of the journal box, sothat the side frame need not be raised or jacked up so high as would otherwise be necessary to permit the jourmailbox to he slipped downwardly out of engagement with the jaws, thus greatly facilitatiug the removal of the journal boxes. axles and wheels from the car truck. All of these parts, in as far as above described, are of well known construction.

The means employed for retaining the journal boxes in place in the side frames are constructed as follows: The depending jaws a a of the side frame are provided with pockets or recesses C which have open sides facing the journal box and in which the holding devices for the journal box are located. Each of these holding devices consists of an arm or block D which is. pivoted in the pocket, preferably by a pivot shaft or pin d driven through a hole in the arm and adaptedto turn in holes in the side walls of the pocket. This arm is adapted to be swung into and out of a recess E formed in the side of the journal box and to bear on a shoulder a at the upper edge of the recess -for holding the box in pace. The pivot shaft (l is provided With a. suitable part, such as a square end (13' located outside the side frame, adapted to be engaged by a suitable tool for turning the shaft to movethe arm D into and out of its holding position.

The arm or block D is preferably provided with means for retaining it in its holding position. In the construction shown for this purpose, the arm or block is made with an end socket and contains a plunger F, which is pressed outwardly by a spring f located within the socket under'the plunger. The end of the plunger is ada "ted to engage ormed in the shoulder c of the journal box for releasably retaining the holding arm in position to hold the box within the jaws of the side frame. When the shaft 03 is turned to move the arm I) out of its holding position, the plunger is forced into the hollow end of the arm by the wedging action of the inclined faces of the groove and the end of the plunger. The arm or block D could be pivoted in the pocket and actuated in other suitable ways, and means of different construction could be employed for releasably holding the arm or blockin its operative holding position.

The recesses E formed in the outer faces of the side walls of the journal boxes coincide with the usual lugs G provided interiorly on' the side walls of the box for retaining the journal brasses in position, so that by forming the recesses E in this manner, a saving in metal is effected, making the box lighter in weight and at the same time providing means whereby the box can be held on the side frame.

Holding means of the described construction are reliable and effective in. operation, since the arm D will be retained in its inclined or holding position by gravity, as well as by the engagement of the spring plunger F in the groove f. The downward pressure of the journal box B on the arms D, due to the weight of the box, wheels and axle, will also tend to move the arms D into tighter engagement with the box. When the arm is in its vertical position, out of engagement with the 'ournal box, as indicated by dotted lines in I ig. 1, the friction of the plunger against the upper Wall of the re cess C will hold the arm in this position.

I claim as my invention: 1. A car truck side frame having jaws adapted to straddle a journal box, a shoulder formed on the journal box, and an arm pivoted on the side frame and adapted to be swung into engagement with said shoulder to retainthe journal box between said jaws, substantially as set forth.

2. A car truck side frame having jaws adapted to straddle a journal box, one of which jaws has a pocket, the open side of' which faces the journal box, a shoulder 40 formedon the journal box, and an arm pivotally mounted in said pocket and adapted to be swung into engagement with said shoulder to retain the journal box between the jaws, substantially as set forth.

3. The combination of a car truck side frame having jaws, a journal box adapted to be held between said jaws and having an inwardly extending projection and a recess I in the outer face of the ournalbox coinciding with said projection, and locking means pivoted on said side frame and adapted to be swung into said recess for holding the journal'box in place between the jaws, substantially as set-forth.

4. A car truck side frame having jaws and means for retaining said arm in holding engagement with said journal box, substantially as set forth.

5. A car truck side frame having jaws adapted to straddle a journal box, a shoulder formed on the journal box, an arm pivoted on the side frame and adapted to be swung into engagement with said shoulder to retain the journal box between said jaws, and a retaining member mounted on said arm and adapted to be pressed into engagement with said journal box for releasably holding the arm in its holding position, substantially as set forth.

6. A car truck side frame having jaws adapted to straddle a journal box, a shoulder formed on the journal box and having a groove, an arm pivoted on theside frame and adapted to swing into engagement with said shoulder, and a spring-pressed plunger mounted to slide lengthwise of the arm and adapted to engage in said groove for yield.- ingly holding the arm in its holding position, substantially as set forth.-

7. A car truck side frame having jaws adapted tostraddle a journal box, one of which jaws has a pocket, the open side of which faces the journal box, a shoulder formed on the journal box, a locking arm in said pocket adapted to'engage said shoulder on the journal box, and a pivot shaft for said locking arm, the end of the shaft I being shaped to engage with a tool for turning the same, substantially as set forth./

Witness my hand, this 13th day of December, 1912.
